CFD Study of Needle Motion Influence on the Spray Conditions of Single-Hole Injectors

Margot, Xandra Marcelle; Hoyas Calvo, Sergio; Fajardo, Pablo; Patouna, Stavroula (Begell House, 2011)

[EN] The spray characteristics and, consequently, the success of the Diesel combustion process is strongly affected by the manner in which fuel is introduced in the combustion chamber. This work consists in studying the ...
Comparative study of the internal flow in diesel injection nozzles at cavitating conditions at different needle lifts with steady and transient simulations approaches

Salvador, Francisco Javier; De La Morena, Joaquín; Crialesi Esposito, Marco; Martínez López, Jorge (SAGE Publications, 2018)

[EN] The motion of the needle during the injection process of a diesel injector has a marked influence on the internal flow, the fuel characteristics at the nozzle exit, the spray pattern and the fuel-air mixing process. ...
Numerical simulation of needle movement nozzle flow coupled with spray for a diesel injector using an Eulerian spray atomization model

Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro; Alarcón-Herrera, Mary Yilbary (Springer-Verlag, 2017)

[EN] The injector dynamics have a strong impact on spray behavior, therefore on combustion efficiency and pollutant emissions. Nozzle flow and spray coupled simulations are useful tools to analyze the effect of nozzle ...
